NEW YORK SPECIES OF CANTHARELLUS. 
CANTHARELLUS dAdaus. 
‘‘Hymenophorum continuous with the stem, descending unchanged 
into the trama. Lamelle thick, fleshy or waxy, fold-like, sub- 
branched, obtuse on the edge. Spores white. Fleshy or membranous 
putrescent fung? destitute of a veil.” Hymen. Europ., p. 455. 
The prominent distinguishing characters of this genus are the 
fleshy substance of the plants and the obtuse edge of the lamelle. 
In nearly all the species these are either dichotomously branched or 
reticulately or anastomosingly connected with each other. They are 
so narrow and thick in some species that they appear more like folds 
or veins than like lamelle. When a transverse section of the lamelle 
is made their fold-like character becomes apparent. The hymenial 
substance covers the entire lower surface of the pileus and hence the 
interspzees are fertile as well as the lamelle. Although some species 
formerly included in this genus are now excluded, ite still contains 
some incongruous members. Thus C. floccosus bears very little 
general resemblance to C. infundibuliformis, and C. aurantiacus looks 
strangely by the side of OC. prudnosus. It has, therefore, seemed best 
to group the species into subgenera or sections according to their 
natural affinities. 
In the section AGaricorbeEs the pileus is fleshy and is rapidly nar- 
rowed below into the stem. The lamelle are very thin and close, 
resembling much those of the Agarici, but they are obtuse on the 
edge and regularly and sometimes repeatedly dichotomous. The 
-species of this group are closely related to the Agarici. 
In EvcanrHareius the pileus is narrowly obconic and tapers 
downward gradually till it is lost in the short stem. Sometimes the 
spreading margin makes it trumpet-shaped. The lamelle are very 
narrow, thick and abundantly and reticulately branched. 
In CanrHaRELLus (proper) the pileus is fleshy, glabrous and more 
horizontally expanded, and the lamelle are broader, more distant, 
and more sparingly branched than in the preceding group. The 
stem is also longer in proportion to the size of the pileus.
